Application filed July 25, l8}? (No model.) I

To aZZ whom z't'may concern. l to supplythe demand ofthe axlein suchman;

Be it known that I, ADDISON BRADFORD, of ner that the said supply willbepure, clean oil, Brooklyn, in the county of Kings and State of devoid ofsuch impurities as would rise if the New York, have invented certain newand use lubricating-wheels were constantly in contact 5 ful Improvementsin 'Lubricators; and I do with the oil, all of whichwill more fullyherehereby declare that the following is a full, inafter appear. A-lubricator for ear axle clear, and exact description thereof, which'journals needs to be so constructed as to be will enable others skilledin the art to which readily applied to the journal while in its .1tappertains to make and use the same, referplace in the journal-box, andreadily adapt IO ence being had to the accompanying drawings, itself tothe varying sizes and shaped boXes and to the letters of referencemarked thereon, and j ournals, also the varying movements and which formpart of this specification. conditions of the journal and box as theyre- This invention relates to mechanical conlate to each other.

The conoil,whereby the lubricating material is prestruction consists of a set ofwheels or rollers vented from becoming gummy and thick, and journaledand mounted between .suitable whereby the desired quantity alone issupplied frame-pieces, said wheels or rollers being jour; to the journaland bearings, as will hereinafter naled in movable bearings adapted toslide in 25 more fully appear. slots or grooves in the framework, andare The invention consists in providing a frame held together "bysprings in connection with of peculiar construction, to which isattached the bearings, so that the wheels are brought waste-preventingrubbers at one end, which close together by the tension of the springs.act spring-like in maintaining said rubbers in The purpose for whichthey are thus journaled 0 contact with the journal, and at the other endand held together is that when in position they are mounted lubricatingrollers or wheels.

These extended arms ing said box withlubricating material through pass on the bottom of the box, under thejoursmall apertures or through some porous manal, till the ends pressagainst the rear end of terial in such quantities as will be sufficientthe box, when the lubricator is raised to an u y right position, and thebail-handle or brace, connected with the upper part of the framework, isplaced inside the end of the box by the door, thus holding thelubricator in a firm upright position. To said arms are attached springswith suitable bearing ends, that bear against the inner portion of thejournals bearing to take off the surplus oil inside the journal-box, toprevent its escape and waste by following the journal outside the box.Fig. 3 shows the frame-work in which the wheels or rollers are journaledin a closed framework, except a suitable opening at the end or elsewhereis covered with a porous substance or perforated material, or a smallhole is left open near the bottom, for the purpose of supplying thewheels with but a moderate amount of oil; also to prevent agitating theoil by running the wheels in it. Fig. 4 shows the journal of therollers'and bearings in section.

In the drawings, A represents a journal-box of a railroad-car, B thebrass or bearing, and G the axle-journal, all of ordinary construction.

On the bottom of the box is the frame D D,

between which are the oilerrolls F F, working on shaft 0, provided withconical journals, and which work in like bearings, 1 which are adaptedto slide in an elongated slot, h, and held in a yielding position bymeans of springs c 0, one being on each side of the frame D D.

Attached to frame D is a hinged frame, F, extending longitudinally alongthe bottom of the box, and to which is attached two vertical springs, IIII, carrying oil-rubbers f f, which are arranged to rub off the oil onjournal, whereby its waste is prevented.

G is a bail or brace secured to space-blocks (Z d in the head of theframe D D, and serves the purpose of support and also of raising andlowering the said head-frame. The frames D .D"' are spaced below by themeans of thimble c.

a b are lugs and pivots whereby the head D D is hinged. v

y, Fig. 3, is an oil-hole to admit oil within the box formed by theframe-head D D; or it may be admitted by means of porous material at theend, as shown by the letter 9'.

The operation of all the above parts will be readily understood from theforegoing description.

Having described my invention and the means of carrying the same intoeffect, I desire to say that many modifications of detail may be madewithin wide range without 'departing from the spirit thereof.

I claim 1. The combination, in a lubricator for carboxes, consisting ofthe yielding lubricatingrollers, pivoted as descnibed, and adapted to bein contact with the journal-bearing for the supply of oil, of thevertical spring supports having the rubbers, also adapted to be incontact with the journal-bearing, for preventing the waste of oil, asset forth.

2. The lubricator for car-axles and the like, consisting of thecarryingframe D D, horizontal frame E, pivoted as set forth, and thespring-rubbers, the former having lubricatingrollers, as set forth.

3. The combination, in a lubricator having the upright frame-head andthe horizontal frame, the former having the elongated slot adapted toreceive the horizontal moving bearings of the oilers, of the springs,whereby the oilrollers may approach to and recede from each other, asshown and described.

4.. A lubricator for railroad-car axles, consisting of the hinged frameshaving the oilers and rubbers, in combination with the bail and brace,as described.

5. A lubricator for car-axles, having the hollow head forming anoil-box, said box being provided with oilinlet apertures for the supplyof oil to the rollers, whereby only sufficient lubricant is fed to theaxles, and with the movable spring-operating ournalbearings for saidrollers, as described.

(3. The combination, with a journal-box, of an oil-receptacle therein,and adapted to have one or more lubricating-rollers, said box beingprovided with controlling oil-inlet aperture, for the purpose set forth.

7. In a lubricator, one or more journaled rollers in asuitable box ordevice, to prevent said rollers from running in the oil outside of saidbox or device, the said box or device being provided with controllingoil inlet or aperture, for the purpose set forth.

8. A lubricator provided with spring-armed oil wiper or rubber, as setforth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

ADDISON BRADFORD.
